Solve the problem. A ball is kicked upward with an initial velocity of 68 feet per second. The ball's height, h (in feet), from the ground is modeled by h = negative 16 t squared + 68 t, where t is measured in seconds. How much time does the ball take to reach its highest point? What is its height at this point?
a.
4.25 sec; 72.25 ft
c.
2.125 sec; 144.5 ft
b.
4.25 sec; 216.75 ft
d.
2.125 sec; 72.25 ft
